摘　　要：以矿井瞬变电磁法在润东煤业东翼胶带巷水患探测为例,在分析探测位置水文地质条件的基础上,结合瞬变电磁法“烟圈效应”设计探测方案。基于TemProcess软件分析原始数据,有效提取二次场信号,实现低阻异常“去伪存真”。将瞬变电磁数据转化为三维数据体,借助Voxler软件实现低阻异常三维成像。经钻探验证,物探解释低阻异常位置与实际情况吻合程度较高,误差在5m内,大幅提高了瞬变电磁探测精度。Taking mine transient electromagnetic method for flood detection in the east wing belt lane of Rundong Coal Industry as an example, on the basis of analyzing the hydrogeological conditions of the detection location, combined with the transient electromagnetic method "smoke ring effect",a detection scheme was designed.Based on the TemProcess software to analyze the original datas, the secondary field signal could be effectively extracted, and the low-resistance anomaly could be "removed and true".Transient electromagnetic dataswere converted into three-dimensional datas volume, and low-resistance anomaly three-dimensional imagingswere realized with the help of Voxler software.It had been verified by drilling that the geophysical interpretation of the low-resistance anomaly had a high degree of agreement with the actual situation, and the error was within 5 m, which greatly improved the accuracy of transient electromagnetic detection.
